The aim of study was to investigate the transformative effect of the COVID-19 pandemic on magnetic resonance imaging (MRI) services in one tertiary cardiovascular center. The retrospective observational cohort study analyzed data of MRI studies ( = 8137) performed from 1 January 2019 to 1 June 2022. A total of 987 patients underwent contrast-enhanced cardiac MRI (CE-CMR). Referrals, clinical characteristics, diagnosis, gender, age, past COVID-19, MRI study protocols, and MRI data were analyzed. The annual absolute numbers and rates of CE-CMR procedures in our center significantly increased from 2019 to 2022 (-value < 0.05). The increasing temporal trends were observed in hypertrophic cardiomyopathy (HCMP) and myocardial fibrosis (-value < 0.05). The CE-CMR findings of myocarditis, acute myocardial infarction, ischemic cardiomyopathy, HCMP, postinfarction cardiosclerosis, and focal myocardial fibrosis prevailed in men compared with the corresponding values in women during the pandemic (-value < 0.05). The frequency of myocardial fibrosis occurrence increased from ~67% in 2019 to ~84% in 2022 (-value < 0.05). The COVID-19 pandemic increased the need for MRI and CE-CMR. Patients with a history of COVID-19 had persistent and newly occurring symptoms of myocardial damage, suggesting chronic cardiac involvement consistent with long COVID-19 requiring continuous follow-up.
本研究的目的是调查新冠疫情对一家三级心血管中心磁共振成像（MRI）服务的变革性影响。这项回顾性观察队列研究分析了2019年1月1日至2022年6月1日期间进行的MRI研究数据（n = 8137）。共有987例患者接受了对比增强心脏MRI（CE-CMR）检查。对转诊情况、临床特征、诊断、性别、年龄、既往新冠病史、MRI研究方案和MRI数据进行了分析。从2019年到2022年，我们中心CE-CMR检查的年度绝对数量和比率显著增加（p值<0.05）。肥厚型心肌病（HCMP）和心肌纤维化的时间趋势呈上升趋势（p值<0.05）。在疫情期间，与女性的相应值相比，男性心肌炎、急性心肌梗死、缺血性心肌病、HCMP、心肌梗死后硬化和局灶性心肌纤维化的CE-CMR表现更为普遍（p值<0.05）。心肌纤维化的发生率从2019年的约67%增加到2022年的约84%（p值<0.05）。新冠疫情增加了对MRI和CE-CMR的需求。有新冠病史的患者出现了持续和新出现的心肌损伤症状，提示与长期新冠一致的慢性心脏受累，需要持续随访。
